Specific probiotics or 'fecal transplantation'.

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The intestinal ecosystem, primarily the enteric flora, significantly influences both intestinal and extraintestinal health.
• Alterations in gut bacteria can trigger local and systemic immune responses, contributing to disease.
• Non-antibiotic interventions for the enteric flora include nutrition, probiotics, and fecal transplantation.

Purpose of the Study:

• To compare the biological consequences, safety, and therapeutic evidence of specific probiotics versus fecal transplantation.
• To explore the potential distinct roles of probiotics and fecal transplantation in treating various diseases.
• To highlight the need for further research into bacteriotherapy for Inflammatory Bowel Disease (IBD).

Main Methods:

• Comparative analysis of existing therapeutic interventions for enteric flora modulation.
• Review of historical data on probiotic use and recent data on fecal transplantation.
• Hypothetical framework based on differing biological activities of probiotics and fecal transplantation.

Main Results:

• Probiotics have a therapeutic history spanning over a century.
• Fecal transplantation is a more recent intervention with limited experience and unclarified safety profiles.
• Distinct biological activities suggest potentially different therapeutic applications for probiotics and fecal transplantation.

Conclusions:

• Probiotics and fecal transplantation represent different approaches to bacteriotherapy with unique characteristics.
• Further research is essential to clarify the safety, efficacy, and specific applications of these therapies, particularly for IBD.
• Understanding the nuances of bacteriotherapy is crucial for advancing treatment strategies for gut microbiome-related disorders.
